Shunsuke Saito

I am a Research Scientist at Reality Labs Research in Pittsburgh, where I lead the effort on next generation digital humans (foundational model, relighting, faces, hands, full-body, hair, clothing, accessories, and more!). For example, I am one of the core contributers of Codec Avatar 2.0, which was featured in Meta Connect 2022 and Lex Fridman's metaverse interview with MZ. If you are interested in an internship with us, feel free to email/DM me!
